LTC1098LCS8#PBF

Analog To Digital Converters (ADC) Overview

The LTC1098LCS8#PBF is a micropower, sampling 8-bit analog-to-digital converter (ADC) manufactured by Analog Devices. It features a successive approximation register (SAR) architecture with a single-ended or pseudo-differential input structure. The device operates on a single 5V supply and supports serial I/O interfaces for data transfer. Key electrical specifications include a maximum sampling rate of 33 kS/s, an integral nonlinearity (INL) of 0.5 LSB, and a differential nonlinearity (DNL) of 1 LSB. The component is housed in an 8-lead SOIC package and is rated for operation within a commercial temperature range of 0°C to +70°C.

• High accuracy: 0.5 LSB INL and 1 LSB DNL
• Compact 8-lead SOIC surface-mount package

Analog To Digital Converters (ADC) Applications

• Battery-powered instrumentation systems
• Portable data acquisition devices
• Industrial process control monitoring
• Low-power sensor signal conditioning

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'LC' against official Analog Devices documentation to confirm the extended industrial temperature range (-40°C to +85°C), as standard 'C' variants are limited to 0°C to +70°C. Confirm RoHS compliance status via the manufacturer's current material declaration. Ensure the ordering part number matches the required packaging format, such as tube or tape and reel, as availability varies by configuration.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC1098LCS8#PBF when low power consumption and moderate speed are critical requirements. This component is suitable for applications requiring a single 5V supply and external voltage references. Compare performance metrics such as SINAD and SFDR against higher-speed alternatives if bandwidth demands exceed 33 kS/s. Verify that the 8-bit resolution meets the system's noise floor requirements before finalizing the design.

Analog To Digital Converters (ADC) Part Context

The LTC1098 belongs to the Linear Technology microPOWER™ series of general-purpose SAR ADCs. It is functionally similar to the LTC1096 but offers higher resolution. The 'LCS8' designation indicates the lead-free, commercial grade variant in an SOIC-8 package. The '#PBF' suffix denotes Pb-free finish and RoHS compliance. This part is often used in conjunction with precision voltage references and operational amplifiers in signal chain designs.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible substitutes include the LTC1098CS8#PBF for commercial temperature ranges. For extended temperature requirements, verify the availability of the LTC1098LCS8#TRPBF in tape and reel packaging. Cross-reference with the LTC1298 for improved performance if power constraints allow.
